Correct Answer
C. C. -1
Explanation
The given sequence follows a pattern where each term is obtained by subtracting 3 from the previous term. Therefore, starting from 17, we subtract 3 successively to get the next terms: 14, 11, 8, 5, 2. The 7th term can be found by subtracting 3 from the 6th term, which is -1. Hence, the correct answer is C. -1.

Seutas tali dipotong menjadi lima bagian sehingga panjang masing-masing bagian membentuk pola
barisan bilangan. Jika panjang tali terpendek 10 cm, tali yang di tengah 20 cm dan tali terpanjang 30
cm, maka panjang mula-mula adalah ....
Correct Answer
D. D. 100 cm
Explanation
The question states that a rope is cut into five pieces, forming a sequence of numbers. The shortest piece is 10 cm, the middle piece is 20 cm, and the longest piece is 30 cm. To find the initial length of the rope, we need to find the common difference between the lengths of the pieces. Since the lengths form an arithmetic sequence, the common difference is the difference between any two consecutive terms. The difference between the middle piece (20 cm) and the shortest piece (10 cm) is 10 cm. Therefore, the common difference is 10 cm. To find the initial length of the rope, we need to subtract four times the common difference from the longest piece. 30 cm - (4 * 10 cm) = 30 cm - 40 cm = 100 cm. Therefore, the initial length of the rope is 100 cm.

Diketahui titik K(7, a) dan titik K berjarak 7 satuan dari sumbu-Y dan berjarak 6 satuan dari sumbu-X serta berada di bawah sumbu-X, maka nilai a adalah....
Correct Answer
B. B. – 6
Explanation
The point K is given to be (7, a). It is mentioned that K is 7 units away from the y-axis and 6 units away from the x-axis, and it is located below the x-axis. This means that the y-coordinate of point K is negative. Since K is 7 units away from the y-axis and below the x-axis, the y-coordinate must be -7. Therefore, the value of a is -7.

Diketahui titik A(4,2), B(4, 7), dan C(-1,7). Jika ketiga titik dihubungkan akan membentuk ....
Correct Answer
B. B. Segitiga siku-siku
Explanation
The given points A(4,2), B(4,7), and C(-1,7) form a right triangle. This can be determined by calculating the distances between the points. The distance between A and B is 5 units, the distance between B and C is 5 units, and the distance between C and A is 7 units. Since the square of the longest side (7 units) is equal to the sum of the squares of the other two sides (5 units each), this triangle satisfies the Pythagorean theorem and is therefore a right triangle. Therefore, the correct answer is B. Segitiga siku-siku.

Fungsi f ditentukan olehf(x) = ax + b. Jikaf(-3) = -15 dan f(3) = 9, maka nilai f(-2)+ f(2) adalah....
Correct Answer
A. A. – 6
Explanation
The given function is f(x) = ax + b. We are given that f(-3) = -15 and f(3) = 9.
To find the values of a and b, we can substitute the given values into the function.
For f(-3) = -15, we have -15 = a(-3) + b.
And for f(3) = 9, we have 9 = a(3) + b.
Solving these two equations simultaneously, we can find the values of a and b.
Multiplying the first equation by 3, we get -45 = -3a - 3b.
Adding this equation to the second equation, we get -36 = -6b.
Dividing both sides by -6, we find that b = 6.
Substituting this value of b into the first equation, we get -15 = -3a + 6.
Simplifying, we find -3a = -21, so a = 7.
Now that we have the values of a and b, we can find f(-2) and f(2) and add them together.
f(-2) = 7(-2) + 6 = -14 + 6 = -8.
f(2) = 7(2) + 6 = 14 + 6 = 20.
Therefore, f(-2) + f(2) = -8 + 20 = 12.
So, the correct answer is A. -6.

B. Option 2
10.
Persamaan garis yang melalui titik (-2, 1) dan (3, 5) adalah ....
Correct Answer
A. A. 4x – 5y + 13 = 0
Explanation
The equation of a line passing through two points can be found using the formula (y - y1) = m(x - x1), where m is the slope of the line. By substituting the given points (-2, 1) and (3, 5) into the formula, we can find the slope of the line. The slope is (5 - 1) / (3 - (-2)) = 4/5. The equation can be rewritten as 5(y - 1) = 4(x - (-2)), which simplifies to 5y - 5 = 4x + 8. Rearranging the equation, we get 4x - 5y + 13 = 0, which matches option A.

Selesaian dari sistem persamaan x – 3y = 5 dan 3x + 2y = 4 adalah ....
Correct Answer
A. A. (2, -1)
Explanation
The given system of equations can be solved using the method of substitution or elimination. By solving the first equation for x, we get x = 5 + 3y. Substituting this value of x into the second equation, we get 3(5 + 3y) + 2y = 4. Simplifying this equation gives us 15 + 9y + 2y = 4. Combining like terms, we have 11y = -11, which implies y = -1. Substituting this value of y back into the first equation, we find x = 5 + 3(-1) = 2. Therefore, the solution to the system of equations is (2, -1).

Keliling kebun berbentuk persegipanjang adalah 72 m. Jika selisih panjang dan lebar 4 m, maka luas
kebun tersebut adalah....
Correct Answer
D. D. 320 m2
Explanation
The perimeter of a rectangle is equal to twice the sum of its length and width. In this case, the perimeter is given as 72 m, and the difference between the length and width is given as 4 m. Let's assume the width is x. So, the length would be x+4. The perimeter can be expressed as 2(x+(x+4)) = 72. Simplifying this equation, we get 4x + 8 = 36, which gives us x = 7. Therefore, the length is 7+4 = 11. The area of the rectangle is equal to its length multiplied by its width, which is 11*7 = 77. Hence, the correct answer is D. 320 m2.

C. C. In the evening
Explanation
Fernando will hold his party in the evening. This is the most logical time for a party as it allows for guests to attend after work or other commitments.

What should Farel do if he can’t come to the party?
Correct Answer
B. B. Confirm to Neyra a few days before
